Description

Light fire-proof glass fiber and magnesia combined partition

Technical field

The present invention relates to a kind of fire proof construction finishing material, particularly a kind of light fire-proof glass fiber and magnesia combined partition.

Technical background

In recent years, the fire proof construction finishing material comes into the market successively, and especially the product that glass magnesium plate and keel are made up as fire partition occupies certain market.But as the main raw in the fire partition of combination---glass magnesium plate exists always and returns serious quality problems such as halogen, scum, thin-skinnedization of plate, anti-folding, tension, the every performance index of resistance to impact shock are lower, because user's the interests that had this problem grievous injury cause this product to be difficult in the market widespread use.After the technician repeatedly analyzes, tests and show: solve above-mentioned serious quality problems, must reselect glass magnesium plate starting material and suitable proportioning, and will grope its manufacture method.

Summary of the invention

In order to solve the quality problems that exist in the above-mentioned prior art,, develop a kind of light-duty fire-resistant glass fiber and magnesia combined partition finally through technician hundreds of inferior test, analyses.This product is through 21 stations, quality supervision and inspection center, Tianjin and the check of material of construction inspection center, and its folding strength is 20Mpa, and tensile strength is 6Mpa, and resistance to impact shock is 8.0kj/m ², have surface halide accumulation resistance, the no globule, nothing is got damp, the requirement that all is up to state standards of every index.Be that fire testing carries out 240min through national fixed fire extinguishing system and fire retarding component quality supervision and test center measured result again, do not lose integrity, carry on the back 70.7 ℃ of the highest average temperature risings of fiery face, 129.7 ℃ of the highest single-point temperature rises, do not lose thermal insulation, fire endurance is greater than 4.00h.

Beneficial effect of the present invention: not only have surface halide accumulation resistance, the no globule, nothing is got damp, thermal insulation is good, fire endurance is higher, advantage such as in light weight, and anti-folding, tension, resistance to impact shock all comply with the national standard requirements, and therefore can be widely used in the required fire proof construction in each field.

(6) cut after will taking off the glass magnesium plate block pattern row pattern of frame, cutting machine is the rail mounted mechanical cutter, glass magnesium plate is piled up compress after neat, carries out the two sides cutting earlier, then carries out other two sides cutting, cutting back plate face is of a size of＜and 2440 * 1220〉mm.

Raw-material effect:

A. magnesium oxide is glass magnesium plate main material, and magnesium content is 85%, and it is in the nature fire-retardant material, bittern is magnesian blender, after adding bittern in the magnesium oxide, plays chemical concentrated expression, can cause the rapid coagulation of magnesium, the concentration of bittern is high more, and cohesion speed is fast more.

B. perlite also for self fire prevention, plays the filler aggregate effect in glass magnesium plate.

C. sulfonated lignin are solid properties-correcting agent, are mainly used in the modification of magnesium chloride material, change system into the magnesium gelatinous material of stable performance with this properties-correcting agent, return shortcomings such as halogen, scum, poor water resistance, buckling deformation to overcome it.

D. talcum powder is increase glass magnesium plate whiteness.

E. fiberglass gridding cloth when glass magnesium plate is made, adds the double glazing fibrous mesh cloth for low alkali grid cloth, and this cloth is the pulling force of reinforcement plate.

F. lining cloth prevents that when the axis of rolling rotates extruding slurry is bonding.

The technical process of fire-proof glass fiber and magnesia plate:

Installation method:

One, gets the raw materials ready

A. fire-proof glass fiber and magnesia plate＜2440 * 1220 * 12〉mm, 75mmC type keel, pure aluminium silicate rock wool.

B. fire-resistant glue, refractory cements, glass seam band, fast silk screw.

Two, install

A. according to the drawing requirement, on ground and roof portion eject position of wallboards.

B. the wall floor leveling will be installed, clean out.

C. keel are connected on request, and become support frame with fast silk screw rivet clasp, roof portion is fixed with band steel welding both sides, and ground is fixing with the angle steel and the pipe that rises.

D. with fast silk screw glass magnesium plate is fixed on support frame one side.

E. the pure aluminium silicate rock wool is filled in anyhow between the keel, fills and leads up, fill out even, compacting.

F. with fast silk screw opposite side glass magnesium plate is fixed on the support frame.

G. use fire-resistant glue, refractory cements, synthetic clay is put on the seam crossing of plate, and is bonding, floating glass seam band then, rolls reality, will be not floating with clay at the point of the fast silk screw retention of seam crossing with perching knife, smears high position and treats to even out after clay solidifies substantially.
